Tired of Aphids on Your Plants? These Handle It for You.
Aphids multiply fast, hide in every crevice, and shrug off most sprays. If you’re looking for real treatment—without residue, resistance, or daily leaf-wiping—lacewing larvae are what you use.
Known as “aphid lions,” these predatory larvae feed nonstop on soft-bodied pests, including aphids, thrips, whiteflies, and more. No waiting. No fluff. Just efficient biological pest control that works on contact.
Green Lacewing Larvae (Live Hatch)
Biological Treatment for Aphids, Thrips, Whiteflies, and More
Each container contains incubated lacewing eggs—timed to start hatching around the time they arrive. Once hatched, the larvae begin hunting immediately.
You’re not getting delicate adults. You’re getting high-intensity predators ready to eat their way through pest colonies as soon as they hit the leaf.
What They Treat
| Pest | Stage Targeted |
|---|---|
| Aphids | All stages – primary target |
| Thrips | Larvae and adults |
| Whiteflies | Eggs, nymphs, adults |
| Mealybugs | Crawlers and soft-bodied stages |
| Spider mites | Opportunistic feeding |
| Fungus gnats | Adults only (limited control) |
Note: Lacewing larvae do not target hard scale or underground pests.
Why Lacewing Larvae for Aphids?
| Reason | What It Means |
|---|---|
| Fast suppression | Larvae feed immediately—no lag |
| No sprays or residue | Safe for food crops and ornamentals |
| Highly mobile hunters | They don’t wait for pests to come to them |
| Self-limiting | Cannibalistic—won’t overpopulate your space |
| Zero re-entry interval | Apply and walk away |
What's in the Container
-
Incubated green lacewing eggs
-
Timed to hatch shortly after shipping
-
Carrier: rice hulls, with emerging larvae mixed in
-
You may not see movement right away—release immediately on arrival
These are predators, not houseguests. If you wait too long, they’ll eat each other.
How to Use
-
Release immediately upon arrival
-
Gently scatter contents across affected plants
-
Leave the container open nearby for late hatchers
-
Do not refrigerate, soak, or mist
-
Avoid using any pesticide or foliar spray 7 days before or after release
Optional: Use a Good Bug Diet to sustain larvae if prey is scarce.
Application Rates
| Use Case | Rate |
|---|---|
| Preventative | 1 larva per sq ft, every 2 weeks |
| Active infestation | 250–500 for indoor setups, 1,000–5,000 per acre |
Repeat weekly during high-pressure periods or early in the plant cycle.
Life Cycle Snapshot
| Stage | Timing |
|---|---|
| Larvae | Hunt for 2–4 weeks |
| Pupation | Cocoon phase lasts 5–7 days |
| Adults | Emerge, mate, and lay new eggs if prey remains |
Larvae do the heavy lifting. Adults are beneficial but short-lived and less aggressive.
Storage
